Quantum teleportation1 faithfully transfers a quantum state between distant nodes in a network,enablingrevolutionary information processing *** underlies the proposals of distributed quantum computing and quantum communication networks.A critical step in the road map towards realizing a global quantumnetwork is to simultaneously realize independent quantum sources,prior entanglement distribution and activefeed-forward operation in a single experimental realization of quantum teleportation in the real world.

Using the data samples of (1310.6 ± 7.2) × 106 J/ψ events and (448.1 ± 2.9) × 106 ψ(3686) events collected with the BESIII detector, we search for the rare decays J/ψ → D0e+e− + c.c. and ψ(3686) → D0e+e− + c.c.. No significant signals are observed and the corresponding upper limits on the branching fractions at the 90% confidence level are determined to be B(J/ψ → D0e+e− + c.c.) −8 and B(ψ(3686) → D0e+e− + c.c.) −7, respectively. Our limit on B(J/ψ → D0e+e− + c.c.) is more stringent by two orders of magnitude than the previous results, and the B(ψ(3686) → D0e+e− + c.c.) is measured for the first time.

Using a sample of 448.1 × 106 ψ(3686) events collected with the BESIII detector, a search for the isospin violating decay ηc → π+π−π0 via ψ(3686) → γηc is presented. No signal is observed, and the upper limit on B(ψ(3686) → γηc) × B(ηc → π+π−π0) is determined to be 1.6 × 10−6 at the 90% confidence level. In addition, a search for η(1405) → f0(980)π0 in ψ(3686) radiative decays is performed. No signal is observed, and the branching fraction B(ψ(3686) → γη(1405))×B(η(1405) → f0(980)π0) × B(f0(980) → π+π−) is calculated to be less than 5.0 × 10−7 at the 90% confidence level.

Using a sample of 1.31×109 J/ψ events collected with the BESIII detector at the BEPCII collider, we study the decays of J/ψ → KSKL and KSKS. The branching fraction of J/ψ → KSKL is determined to be B(J/ψ → KSKL) = (1.93 ± 0.01 (stat.) ± 0.05 (syst.)) × 10−4, which significantly improves on previous measurements. No clear signal is observed for the J/ψ → KSKS process, and the upper limit at the 95% confidence level for its branching fraction is determined to be B(J/ψ → KSKS) −8, which improves on the previous searches by 2 orders in magnitude and reaches the order of the Einstein-Podolsky-Rosen expectation.

We report the first observation of the decay Λ+c → Σ−π+π+π0, based on data obtained in e+e− annihilations with an integrated luminosity of 567 pb−1 at √s = 4.6 GeV. The data were collected with the BESIII detector at the BEPCII storage rings. The absolute branching fraction B(Λ+c → Σ−π+π+π0) is determined to be (2.11 ± 0.33(stat.) ± 0.14(syst.))%. In addition, an improved measurement of B(Λ+c → Σ−π+π+) is determined as (1.81 ± 0.17(stat.) ± 0.09(syst.))%. Copyright © 2017, The Authors. All rights reserved.

Using e+e− collision data collected with the BESIII detector at the BEPCII collider corresponding to an integrated luminosity of 5.2 fb−1 at center-of-mass energies (√s) from 4.009 to 4.600 GeV, the process e+e− → π0π0ψ(3686) is studied for the first time. The corresponding Born cross sections are measured and found to be half of those of the reaction e+e− → π+π−ψ(3686). This is consistent with the expectation from isospin symmetry. Furthermore, the Dalitz plots for π0π0ψ(3686) are accordant with those of π+π−ψ(3686) at all energy points, and a neutral analogue to the structure in π±ψ(3686) around 4040 MeV/c2 first observed at √s = 4.416 GeV is observed in the isospin neutral mode at the same energy.
